Sleep talking, clinically known as somniloquy, involves vocalizations during sleep. These can range from simple mumbling to elaborate sentences, and may occur during any sleep stage. The content of these utterances often bears little relation to the individual’s conscious thoughts or experiences.
While generally harmless, sleep talking can sometimes be disruptive to bed partners or roommates. Historically, it was often attributed to spiritual or psychological distress. Current understanding recognizes it as a parasomnia, a sleep disorder characterized by abnormal behaviors during sleep. Understanding the triggers and patterns can aid in managing potential disturbances.
